DHHIIHNQ lllllECl-lANIISWl FOR HARVESTEH PEELS.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed July 10, 1905. Serial No. 268,930.

To a, whom it may concern.-

Be it known that I, J AMES A. SHARP, a citizen of the United States, residing at Harvey, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Driving Mechanism for Harvester Reels, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to driving mechanism for harvester-reels, and is particularly applicable to machines of that general class in which the cutting apparatus, grain-platform, reel, and elevator mechanism'are in advance of the drive-wheel, the machine being propelled by what is commonly called a pushpole.

It consists in a reel adjustably mounted upon a suitable carrying-frame and driven by means of a flexible shaft extending in a foreand-aft direction provided with a pinion at one end engaging with a gear member secured to the reel-shaft and having its opposite end free to slide through the hub of a sprocketwheel or other gear member journaled in a fixed bearing secured to the reel-carrying frame and giving motion to the flexible shaft, the sprocket-wheel deriving motion by means of a chain connection with a sprocl'ret-wheel secured to the rear end of the stubbleward roller of the endless carrier of the grain-receiving platform, that receives motion from the power-transmitting means connected with the drive-wheel in a common manner, the object of the invention being to provide a mechanism having less parts and one permitting the adjustment of the reel in any desired direction without interfering with the operative effect of said mechanism. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which Figure 1 is an end elevation, partly in section, of part of a harvester embodying my invention. Fig. 2 is a fragmentary view of part of Fig. l on line A B, and Figs. 3 and 4: represent details of the reel-driving mechanism.

Similar numerals refer to similar parts throughout the several views. Y

1 is the drive-wheel, mounted in a suitable frame, having a forwardly-projecting grainplatform 2, provided with the usual endless apron-carrier, for delivering the grain to the elevator. (Not shown.) Motion is transmitted from the drive-wheel to a common form of gear mechanism 3, supported by the frame in rear of the drive-wheel, and which transmits motion to the carrier-rollers of the platform and elevator by means of the shafts 4; and 5, respectively.

6 is a vertically-arranged frame member, secured to the platform and supported by the brace-bar 7.

8 is a forwardly-projecting reel-sup porting arm, secured at its rear end to the member 6 and having the brace member 9 secured tl1ereto and to the upper end of the member 6. The reel-shaft 10 is journaled in a bearing 11 at its stubbleward end, that is adjustably mounted upon the forward end of the arm 8. Secured to the reel-shaft is a bevel-wheel 12, and meshing therewith is a pinion 13, secured to one end of a shaft 14:, that is journaled in an arm 15, rotatably mounted upon the reelshaft adjacent the bevel-wheel 12. The opposite end of the shaft is flexibly connected, by means of a universal coupling 16, with a square shaft 17.

Secured to the vertical member 6 is a journal-box 18,'and 19 is a sprocket-wheel provided with a laterally-extended hub portion that is journaled in the box 18 and provided with an axial angular opening adapted to receive the square shaft 17 in a slidable manner. The wheel is secured against movement away from the box by means of the collar. 20, secured to the end of the journal portion by means of the set-screws 21 at one side of the journal-box.

Referring to Fig. 2, 22 is a sprocket-wheel secured to a shaft 23, that derives motion from the gear mechanism by means of the shaft 4, as previously stated, and in this construction the lower roller 24: of the lower elevator-carrier is carried by shaft 23. The sprocketwheel 22 transmits motion to sprocket-wheel 25, secured to the end of a shaft 26, upon which the carrier-roller 27, at the stubbleward end of the grain-platform, is mounted by means of a sprocket-chain 28. Mounted upon the extended end of the shaft 26 is a sprocket-wheel 29, and a sprocket-chain 30 connects it with the sprocket-wheel 19 at the rear end of the reel-driving shaft, and 31 is a chain-tightener adjustably mounted on the member 6 and engaging with the chain 30.

The reel-shaft may be adjusted in a fore-andaft direction upon the supporting-frame in 'frame member in rear of said platform, a

its rear end secured to said vertically-arranged any of the common ways, and the frame may l be constructed in any desired manner. I have shown the bearing 11 to be adjustable along the arm 8 by means of the opening therein, as shown in Fig. 3. Vhen the reel is adjusted in either direction along the bar, the shaft 17 will slide through the hub of the sprocket-Wheel '19, and the universal coupling 16 between the two members of the shaft will allow the shaft 14: to assume an angle with the part 17 and prevent any cramping of the same and the sprocket-wheel 19 in its bearing.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a harvester, the combination of a main drive-wheel, a grain-platform located in front of said drive-wheel and comprising carrierrollers, means for transmitting motion from' said wheel to said rollers, a vertically-arranged forwardly-projecting frame member having member, a reel-shaft adjustably mounted at the forward end of said second-named frame member, a bevel gear-wheel secured to said shaft, a two-part shaft having its adjacent ends connected by means of a universal coupling, the forward end of said shaft being journaled in an arm rotatably mounted on the reel-shaft, a bevel-pinion secured to said shaft and engaging with said bevel-wheel, a journal-box secured to said vertically-arranged frame member, a sprocket-wheel journaled in said box, the rear end of said two-part shaft slidably mounted in said sprocket- Wheel, means for driving said sprocket-wheel comprising a sprocket-Wheel secured to the rear end of one of said carrier-rollers and a chain connection between the two sprocket-wheels.

In witness whereof 1 hereto affix my signature in presence of two witnesses.
